SPECIFICATION forming part of Letters Patent No. 236,028, dated December 28, 1880.

9 Application filed November 8, 1880. (No model.)

To all whom it may concern:

Be it known that I, JONAS HERRMANN, of Columbus. Franklin county, State of Ohio, llaveinvented a new and useful Improvement in Window-Cornices, of which the following is a specification.

My invention in window-cornices relates to that class which may be adjusted so as to adapt them to fit windows of different widths.

In the drawings, Figure 1 is a rear elevation of a window-cornice embodying my improvements, the locking-levers being turned down and the parts locked in one position. Fig. 2 is a top view of Fig. 1, partly in section and Figs. 3 and 4 sections of Fig. 2 on the dotted lines a; wand yy, respectively, looking in the direction of the arrow.

Similar letters of reference indicate corresponding parts.

The center-piece or bracket A, of suitable size, shape, and ornamentation, is provided at its rear base portion with a tongued and grooved slide, a, made of thin metal bent at one end and entered into the wood, as shown in Fig. 3, this construction forming a neat and durable base for the cornice, as well as a nonwarpable and effective guide for the sliding pieces B B.

The adjustable pieces B B, of suitable len gth, have formed on their under edge a tongue and groove, to ride in the tongue and groove of the metal slide a. Upon the faces of the adjustable pieces B B are cut lines oflocking-grooves, that also form a measuringscale, as designated by the figures 1 2 3, &c., Fig. 1, the grooves being arranged at definite distances from each other, as, say, one inch or more.

Fastened to the cleat b, forming the upper guide-bar for the adjustable pieces B B, are two plates, 0 c, which serve as guides for the pieces B B. These plates 0 c are provided with ears 6 6, upon which are pivoted lockinglevers f f, the short ends of said locking-levers being rounded so as to readily enter the slots or locking-grooves in the adjustable pieces B B. These locking-levers ff also serve as pointers by which to regulate the adjustment 1 of the pieces B B.

\ When desired to adjust the cornice to a given lengthsay, for instance, three inchesthe levers are raised and the adjustable pieces moved along until the numbers 1% 1%, designating the number of inches and fractions traversed by each pieceB B, are directly in line with the pointers. Then the levers ff are pulled down, their short ends enter the slots 1% 1%, and the parts are securely locked. (See Figs. 2 and 3.)

At the ends I have provided metallic miterplates 9 g, with elongated slots h, for the reception of the headed pins or screws i upon the end pieces, 0 O, this forming a simple adjustable connection and making a finished miterjoint, by which the end pieces maybe attached to the cornice-pieces B B. This method of uniting the end pieces permits of their convenient removal and substitution of longer or shorter end pieces whenever desired.

Having thus described myinvention,Iclaim as new and desire to secure by Letters Patent- 1. In an adjustable cornice, the combination, with bracket A and its metallic tongued and grooved pieces B B, guiding-plates c c, and locking-levers ff, substantially as described.

2. In an adjustable cornice, the adjustable pieces B B, provided with the grooved scale, in combination with the locking-levers ff to enter the grooves of the scale, substantially as described.

3. In an adjustable cornice, the herein-described locking-leversff, provided with plates 0 c, to carry said levers and also guide the adjustable pieces B B, as shown and described.
